TIMING DEVICE.

Specification of Letters Patent. Patented Feb. 27, 1912..

Application filed January 14, 1910. Serial No. 538,000.

To all whom it may concern I Be it known that I, CHARLES F. WHITE, a citizen of the United States, and a resident of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Timing Devices, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to timing devices such as used at racing events, wherein a stop watch is actuated electrically to indicate the time consumed by a racer traversing the track from the starting line to the finishing line.

The principal objects of this invention are to more accurately. determine the exact time consumed in traversing a certain predetermined course, and to accurately indicate at different stations contemporaneously, the precise moments at which said racer actually started and finished the race, and the time intervening between said start and finish, to provide means wherebythe racer automatically actuates the mechanism for actuating the time pieces by his movements across the predetermined lines, and to provide portable mechanism that can be conveniently carried in a small hand case, and readily and speedily set in operative position.

The form of this invention hereinafter described provides a case inclosing timing mechanism adapted to be located at the starters station, and a case inclosing timing mechanism adapted to belocated at the judges stand, each inclosing a stop watch controlled by a centrally pivoted lever, whichv is actuated by an electromagnet, and a switch which is connected with a fragile tape arranged to'extend across the path ofthe racer and to be broken by his movement, and arranged to shift said switch to close thecircuit through said magnet.

The magnets-inclosed by the cases disposed at the respective starting and stopping stations are electrically connected, so that the watches at each station are contemporaneously started or stopped by the breaking of the tape respectively at the starters station or at the judges stand.

In the accompanying drawings, Figure 1 is a perspective view of timing mechanism conveniently embodying the improvements, suitably disposed on posts arranged in operative relation with a race track; Fig. 2

is a top plan View of the timing case which .is arranged to be located at the starters station shown at the left of Fig. 1; Fig. 3 is a horizontal sectional View taken slightly below the upper wall of the case shown in Fig. 2; Fig. 4 is a vertical longitudinal sec- 'tional view of the case shown-in Fig. 2, taken on the line 4-4 in said figure; Fig. 5 is a vertical longitudinal sectional view similar to Fig. 4, of the timing case located at .the judges stand shown at the right of Fig. 3; Fig. 6 is a top plan View of a carrier case into which the timing cases and their batteries may be packed and conveniently carried, said carrying case being shown with its lid open; Fig. 7 is a'diagrammatic view showing the wiring connections.

In said figures, the race track 8 comprises the opposed posts 9 and 10 upon opposite sides of said track at the starters station, and the posts 11 and 12 upon the opposite sides of said track at the judges stand, and the post 13 conveniently located opposite to the spectators stand.

The timing cases 14 and 15 are respectively located at the starters station and judges stand, and are arranged to be respectively mounted on the posts" 9 and 11. Said timing case 14 is provided with the fragile tape 16, which extends therefrom, through the eye 17 and across the track 8 a short distance above said track, and may be tied to the pin 18 on the post 10. The timing box 15 is provided with the fragile tape 20, which extends across the track and may be tied to the pin 21, extending from the post 12. I

v The timing cases 14 and 15 are conven I iently connected by the line wires 22, 23 and 24, and the circuit includes the battery 25, inclosed in the battery box 26, and said line wires may include the branches 27, 28 and 29 extending to the spectators clock 30.

The timing case 14, shown in Figs. 2, 3 and 4, is provided with a singlestroke starting bell 31, connected by the wires 32 and 33 with the push bulb 34, whereby the racer is given the signal to start, said bell being used in place of the usual pistol shot signal. The bell 31 is conveniently mounted on the top wall of the timing case 14, whereby it is visible through the aperture 37 and having its controlling stem 38, arranged to be successively pressed to alternately start and stop said Watch by the oscillation of a con trally pivoted lever 39, having one end overhanging the stem 38 or said watch, and the other end forming the armature of an electromagnet 4E0. Said magnet i6 is arranged to be controlled by the switch 43 having the respective terminals 45 and 46.

The timing case 15incloses the mechanism including the hinged non-magnetic socket 50 arranged to receive the stop watch 51 having the controlling stem 52 arranged to be successively pressed to alternately start and stop said watch by the oscillation of a centrally pivoted lever 53- having one end overhanging the stem 52 of said watch and the other end forming the armature ot the electromagnet 55, said magnet being arranged to be controlled by the switch 56 having respective terminals 57 and 58. Each of the cases it and 15 are provided the apertures 59, of such term as to engage the heads of suitably spaced nails or headed pins driven into the posts 9 and ll, whereby said cases are conveniently sup ported, The timing case 15 is provided. with to wall, and connected in circuit with the magnet 55 in said case, so that when said magnet is actuated by the starting or finish or the race a signal is given by the ring ing of said bell.

The wiring connections will best understood with reference to l5 Z of the drawing, wherein one terminal or a magnet d6 is connected through the battery by the line wire 22, with one terminal or the magnet 55. The other terminal or the magnet being connected to the terminal of the switch s3, and is connected through the line wire 2 with the terminal 58 of the switch 56 at the judges stand The other terminal of the magnet is connected by the wire 63 with the terminal 57 of the switch 56 and through the line wire 23 with the terminal 46 oi the switch 43 at the starters station The signal bell 31 is connected through the battery 25, line wire 22,, line wire 23, terminal 46 and connector 33 with the push bulb 3 so that said bell 31 may be sounded without aiiecting any of the stop watch actuating mechanism, while the bell which is mounted on the timing case the judges stand is connected in series with the magnet 55 so as to be sounded contemporaneously with the closing either the switch 43 at the sta .s station or the switch 56, at the judges stand The switch 4-3 is arranged to be closed by draw ing the tape 16 taut and distorting the leaf spring of the terminal 46 againstthe least spring or" the terminal 45; and the switch 56 5 is arranged to be closed by. drawing the tape bell 60 mounted exterior thereto on its 20 taut and distorting the leaf spring con nected with the terminal 58 against the leai spring connected with the terminal-57.

It may be here noted that the alternate momentary closing of the circuit above described, alternately starts and stops the stop watches 36, so that, as may be readily seen when the racer breaks the tape 16 by his starting movement, the circuit is momentarily closed through the magnets ll) and 55, of the respective timing cases 14: and 15, which by shifting their respective levers 39 and 53, starts the stop watches at both the starters station and the judges stand simultaneously, and also starts the spectators clock 30; and the breaking of the tape 20 at the judges stand actuates the respective levers 39 and 53 at the respective stations,'and contemporaneously stops each cit said stop watches; so that it is unnecessary to go from one station to another to ascertain the difference in time from the starting to the finishing or the race, as said time is plainly indicated at each of the stations, and being elect i ally connected, the time pieces absolutely indicate the same time 1 As shown-in Fig, 6, the carrying case '35 is arranged to receive both of the cases 1&- and 15, and the battery box 26, including the batteries 25. Said carrying case is con veniently provided with a hinged lid 'Zl,

having the hinges and the handle 73 by which it is carried when said lid 71 is closed, and its hooks 7d are engaged the pins 75, whereby the whole apparatusis portable. 'lt is not desired to limit this application to the precise details of construction and arrangement herein set forth, as it is obvious that various modifications may be made herein without departing from the essenhe appended claims.
